<code> blocks should get split automatically to avoid exceeding the 10k record size limit

[octogonz]

What is the current behavior?

Large <code> blocks cause an error: "The jekyll-algolia plugin detected that one of your records exceeds the 10.00 Kb record size limit."

What is your expected behavior?

jekyll-algolia should automatically split these blocks into smaller records to avoid exceeding the size limit.

These <code> blocks are coming from Markdown ``` blocks. So there isn't a straightforward way for me to split them up: additional chunks would be visually rendered with separate borders around them. Whereas it seems that jekyll-algolia could do this pretty easily. It doesn't really matter where it chooses to split the code. I just want my search index to be able to find the page that contains that text.
